H. J. Bernard Combrink, "The Structure of the Gospel of Matthew as Narrative," Tyndale Bulletin 34 (1983): 61-90.

Combrink suggests that the Gospel of Matthew may be arranged chiastically. He points to several textual indicators which support his conclusion and notes that the "narrative plot" (Setting... Complication... Resolution) correlates remarkably with the symmetrical structure.

Interesting if unconvincing.
